To all lwhom, it may concern:

Be it known that I, FREDERIC G. NIcoLAUs, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Lighters for Gas-Stoves, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements 1n lighters for gas stoves.

The object of my invention is to provide a lighter located between the four burners of a gas stove and so arranged that the flame from the lighter will travel across to the burners and ignite the same and also providing a. pilot-light so arranged that the lighter will instantaneously ignite therefrom.

Another object of my invention is to provide a lighter of this character which will produce two flashes during the single operation of the valve, thus if the burners are not ignited from the first flash, they will be by the second flash and thus produce a more effective lighter of this character.

A further object of my invention is to provide a lighter of this character in which the bell carried by the lighter is constructed to supply the proper amount of air to the lighter and at the same time prevent any drippings from the stove from entering the bell and clogging the lighter.

A still further object of my invention is to provide a simple, cheap and effective lighter of this character adapted to he readily applied to the ordinary stove and having certain details of structure and operation hereinafter more fully set forth.

In the accompanying (.lrawings-Figurel is a perspective view of my improved lighter. Fig. 2 is a bottom plan view partly in section. the gas controlling valve.. showing the several parts in their dissembled relation. Fig. 4 is a vertical longitudinal sectional view of the lighter shown in Fig. 1. Fig. 5 is a horizontal sectional view of the lighter proper', showing the relative position of the openings in the burner and the bell and the position of the burners in respect thereto. Fig. 6 is a perspective view of the` burner tip and bell-in their dissembled position.

Referring now to the drawings, 1 represents my improved turning valve, which has Fig. 3 is a perspective .'iew ofits outer end screw-threaded and adapted to be connected to the gas supply of thestove, as is readily understood by those skilled in the art. The casing' of the valve 1 is provided with an off-set portion 3 provided with a tapering opening 4, therethrough and into which fits the turning plug 5 having a transverse curved opening 6, adapted to communicate with the passage 7 leading to the rear of the casing and the passage 8 leading to the forward end of the casing. The plug above the casing is provided with a. circular housing 9, in which is arranged a coiled spring 10, having one endA securely fastened to the plug at 11 and the opposite end has a hooked portion 12, adapted to engage the pin 13, carried by the casing and whereby the plug is at all times held in the closed position in Fig. 2 of the drawings. The plug 4, below the lower end of the housing, is screw-threaded and has a coiled spring 14 surrounding the same. The said coiled spring bears against the lower face of the casing and has its opposite end bearing against the nut 15, screwed upon the lowerthreaded end of the plug 5. By this structure it will be seen that the spring normally holds the plug 4 in its downward position forming a tight joint with the opening 4 in the casing 2, to prevent the leakage of gas therearound. As heretofore stated, the

spring 10 normally holds the plug in the position shown in Fig. 2 and when the plug is turned by means of the handle 16 and the opening G allows the gas to pass from the passage G to the passage 8 to supply the lighter with gas. Vhen the handle 16 has heen turned to the left as far as it will travel, the opening 6 assumes the position shown in d r ted lines, Fig. 2, and the spring has been compressed. Upon releasing the handle 16, the spring carries the turning plug 4, back to the position shown in full line Fig. 2, and in its travel allows a certain amount of gas to pass through the passage 6 to the passage 8 for supplying the lighter with gas.

The casing of my improved valve is provided with a straight opening 17 therethrough and the rear end of the passage 7 communicates.therewith, as fully shown in Fig. 2 of the drawings. The forward end of the casing is provided with a large internail;v sc1'e\\'tl1readed opening 18 with which communicates the passage 17 and 8, and are screwed into the said opening is the main gas supply pipe 19 leading upwardly to a point between the four burners of the stove, as will be later described. The valve casing 1 is provided with a screw valve 20, which is adapted to intercept the passage 8 and to regulate the flow of gas to the main supply pipe 19. The passage 17 is provided with a screw valve 21,which is adapted to regulate the iow of gas to the pilot-light pipe 22, fully shown in Fig. 2 of the drawing. It will be seen from the structure herein shown that the passage 17- supplying gas to the pilotlight burner, hereinafter' more fully described, through the pipe 22, is at all times in communication with the gas supply and, therefore, the pilot-light is continuously burning. The pipe 19 is curved downwardly at 23 and u wardly at 24, and screw-threaded at 25. crewed upon the threaded portion 25 is the main lighter burner 26. This burner has a squared portion 27 resting upon a central depressed squared portion 28 in the lower end of the bell 29 and is locked therein by means of the nut 30, screwed upon the threaded extension 31 of the main burner 26. The main burner is provided with four openings 32, arranged opposite the openings 33 in the bell and whereby when the pipe 19 is supplied with gas through the turning plug 5, as heretofore described, the flame will shoot out from the openings 32 and through the openings 33 in the bell and travel across to the burners 34 and ignite the same. Owing to the squared portion 27 of the burner and the squared depressed portion 28 of the bell 29, the burner tip cannot be placed within the bell in any other position except that with the opening 32 opposite the openings 33, so that the flash of the gas from the openings 32 will travel outwardly through the openings 33 and ignite the burners.

The bell 29, as heretofore described, has the squared portion 28 receiving the contracted lower squared portion 27 of the burner and the burner being attached to the pipe 19, it will be seen that the bell is supported by the burner. The upper end of the bell has ears or lugs 32 struck from the side wall thereof and upon which is mounted the cap 33', having a downwardly extending flange 34, frictionally supported by the ears or lugs 32. These ears form a space between the side wall of the bell and the down-- wardly turned flange 34 of the cap to allow the proper amount of air to pass to the bell causing the proper combustion of the gas as it passes from the opening in the burner. The cap, as shown in Fig. 4 of the drawing, extends over beyond the side Wall of the bell and prevents any dripping from the stove entering the bell and clogging the burner and allows said drippings to drop down off of the bell.

The pipe 22, as shown in Fig. 4 of the drawing, has its end screw-threaded as indicated at 25, and is screwed into the passage 17. The pipe Within the bent portion 23 of the pipe 19 is in the form of a wave as indicated at 35 and placed within thepipe 19, when the said pipe is straight. By this crimping of the pipe 22 at 35, it will be seen that when the pipe 19 is bent, as indicated at 23, the crinips allow for the extension of the pipe 22 to allow the threaded portion 35 to extend beyond so as to be screwed into the opening 17 and also allow for the portion 36 to extend within the burner 26 and be flush' with the upper end thereof, as fully shown in Fig. 4 of the drawings. The portion 35 and the portion 36 of the pipe 22 have to extend a predetermined distance beyond the ends of the pipe 19, so that connection can vbe made with the valve casing, shown in Fig. 2 of the drawings and also to have the upper end of the portion 36 of the `pipe flush with the upper end of the burner 2G, as fully shown in Fig. 4: of the drawings. During the bending operation of the pipe 19, the extended ends of the pipe 22 are held the predetermined distance out of the pipe 19 and the material required for the bending of the pipe 19 at 23 is compensated for by the form of a wave 35.

From the foregoing description, it will be seen that the gas from the main supply is always passing through the passage 17 to the pipe 22 and burning from the open end 36 of the burner, thus forming a pilot light. When it is desired to ignite one of the main burners the plug 5 is turned through the medium of the handle 16, which causes the passage 6 to register with the passage 7 in the valve casing for a short period of time and allows a certain amount of gas to pass to the pipe 19 and the gas then passes outwardly through the openings in the burner 26 and is ignited by the pilot light and flashes outwardly through the openings in the bell 29 some distance therefrom and ignites the main burners arranged opposite the openings. When the handle is released the spring 10 causes the plug 5 to turn backward to the position shown in Fig. 2 of the drawings, which allows another supply of gas to pass through the plug 5 to the pipe 19 and thus cause another flash from the lighter which would light the burners in case they had not been lighted by the first flash.
